Title: ADAPTIVE GUIDANCE SYSTEM FOR VENTRICULAR SEPTAL DEFECT OCCLUSION UNDER ULTRASOUND GUIDANCE
Abstract:
An adaptive guidance system for ventricular septal defect occlusion under ultrasound guidance belongs to the field of the medical technology. The system comprises a guide wire, an outer catheter used for guiding an inner catheter (FH) and transporting an occlusion device, the inner catheter (FH) used for guiding the guide wire and a loading sheath (KM) used for storing the occlusion device. The guiding system and the occlusion can use ultrasound as a unique guiding means, under the ultrasound guidance, insert the guide wire and the catheters to a heart after puncturing via a femoral vein or incision, totally independent from radiation rays, and place the occlusion device at a lesion location through the catheters after passing through a ventricular septal defect from a right ventricle surface, overcoming a problem in prior art that radiation rays are used as guidance media and damages are caused by radiation and contrast agent.
